Description

Technical Field

[0001] The utility model relates to the technical field of garbage disposal, in particular to a clogging monitoring device for a slag discharge shaft of an incinerator. Background Art

[0002] The end of the waste incinerator is connected to a slag discharge shaft, and at the bottom of the slag discharge shaft is a slag discharge machine, which is connected to a slag discharge belt conveyor through a slag discharge channel. The garbage is continuously burned on the grate of the incinerator, and the incinerated garbage forms ash slag, which falls down through the slag discharge shaft to the operating range of the slag discharge machine. The slag discharge machine reciprocates, and can continuously push the ash forward, so that it flows along the slag discharge channel to the slag discharge belt conveyor, and finally sent to the slag pit. Figure 1 shown.

[0003] Since the slag discharge shaft channel is long and the composition of garbage is complex, it is inevitable that there are foreign objects that are difficult to burn in the garbage, such as steel wires, long rod-shaped objects, etc. Once the foreign objects that are difficult to burn pass through the slag discharge shaft, they will inevitably lie horizontally in the shaft or hook on the inner wall of the shaft, affecting the flow of other ash and slag, and even causing the slag discharge channel to be blocked. In daily work, manual regular inspections are required to check whether the slag discharge shaft is blocked, which undoubtedly consumes manpower. For this reason, a slag discharge shaft blockage monitoring device for an incinerator is proposed. Summary of the invention

[0004] In order to solve the problem of manual and labor-intensive periodic inspection of whether a slag discharge shaft is blocked, the utility model provides a slag discharge shaft blockage monitoring device for an incinerator. A monitoring sensor is installed in a slag discharge channel to monitor the flow state of ash and slag, so as to determine whether the slag discharge shaft is blocked.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A device for monitoring the blockage of a slag discharge shaft of an incinerator, comprising a sensor assembly installed in a slag discharge channel and a controller installed in a main control room;

[0007] The sensor assembly includes a load-bearing plate for carrying ash and slag flowing through, a monitoring sensor and a compression spring. The upper part of the load-bearing plate is rotatably arranged in the slag discharge channel. The compression spring is arranged between the lower part of the load-bearing plate and the side wall of the slag discharge channel to facilitate the force-bearing rotation of the load-bearing plate. The load-bearing plate and the side wall of the slag discharge channel enclose a triangular installation space;

[0008] The monitoring sensor for monitoring the rotation of the load-bearing plate is arranged on the inner wall of the slag discharge channel. The monitoring sensor is located in the installation space. The monitoring sensor is connected to the controller to facilitate transmitting the monitoring signal to the controller.

[0009] Furthermore, the length of the load-bearing plate is equal to the width of the slag discharge channel, so that the ash and slag can flow through the load-bearing plate. The load-bearing plate includes a rotating shaft and a rectangular plate body arranged on the rotating shaft.

[0010] Mounting bolts are arranged at both ends of the rotating shaft, and the bearing plate is rotatably connected between the two side walls of the slag discharge channel through the two mounting bolts, so as to facilitate the rotatable installation of the bearing plate.

[0011] Furthermore, a transition thin plate is provided in the slag discharge channel, and the transition thin plate is bent and overlapped on the rotating shaft above the load-bearing plate, so as to facilitate the ash and slag to smoothly enter the load-bearing plate without blocking the rotation of the load-bearing plate.

[0012] Furthermore, the load-bearing plate is arranged at an angle to facilitate the ash to slide off the load-bearing plate, and a variable angle is formed between the side wall of the slag discharge channel where the monitoring sensor is located and the load-bearing plate. The variable angle is due to the pressure of the ash. When there is no ash on the load-bearing plate, the load-bearing plate maintains a fixed angle under the action of the compression spring. At this time, the load-bearing plate does not contact the monitoring sensor, and the monitoring sensor is a micro switch.

[0013] Furthermore, a plurality of limit bolts are arranged at intervals below the load-bearing plate, and the plurality of limit bolts are arranged along the length direction of the load-bearing plate. Each limit bolt passes through the load-bearing plate and is connected to a compression spring. The compression spring is sleeved on the limit bolt to facilitate the installation and fixation of the compression spring. Both ends of the compression spring are tightly pressed between the load-bearing plate and the inner wall of the slag discharge channel, and the compression spring provides a certain elastic supporting force for the load-bearing plate.

[0014] Furthermore, guide plates are symmetrically arranged on both sides of the load-bearing plate, and the guide plates on both sides are arranged in an inverted "eight" shape. The guide plates and the load-bearing plates are surrounded to form a chute structure, which facilitates the ash to flow along the middle position of the load-bearing plate. The height of the guide plates gradually increases along the ash flow direction.

[0015] Through the above technical solution, the beneficial effects of the utility model are:

[0016] The utility model has a reasonable structural design, and a sensor assembly is installed in the slag discharge channel. The sensor assembly is composed of a load-bearing plate rotatably arranged in the slag discharge channel, a compression spring for elastically supporting the load-bearing plate, and a monitoring sensor for monitoring whether the load-bearing plate is under pressure. When the ash slag flows normally in the slag discharge channel, the ash slag must pass through the load-bearing plate and exert a certain pressure on the load-bearing plate to deflect it. After the load-bearing plate is deflected, it contacts the monitoring sensor to transmit a signal to the controller in the main control room. Once the ash slag flow is abnormal, the ash slag will not flow to the position of the load-bearing plate and no longer exert pressure on the load-bearing plate. Therefore, under the action of the restoring force of the compression spring, the load-bearing plate does not contact the monitoring sensor for a long time, and the controller can also get a signal. The personnel can judge that the slag discharge shaft may be blocked according to the signal monitored by the controller, and then arrange personnel to deal with it in time. Through the mutual cooperation of the sensor assembly and the controller, the utility model can automatically monitor the flow condition of the ash slag, thereby judging whether the slag discharge shaft may be blocked, avoiding the tedious operation of manual regular inspection, saving manpower, and having certain application prospects.

DETAILED DESCRIPTION

[0022] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0023] like Figure 2~Figure 4As shown, a device for monitoring the blockage of a slag shaft of an incinerator includes a sensor component installed in a slag channel 4 and a controller 6 installed in a main control room. The sensor component monitors the flow of slag in the slag channel 4, and the monitoring signal is transmitted to the controller 6. Personnel in the main control room can directly understand the flow of slag, thereby determining whether the slag shaft 2 is blocked.

[0024] When the ash flows in the slag discharge channel 4, it passes through the sensor assembly, which includes a load-bearing plate 7 for carrying the ash to flow through, a monitoring sensor 8 and a compression spring 9. The length of the load-bearing plate 7 is equal to the width of the slag discharge channel 4, so all the ash must pass through the load-bearing plate 7. When the load-bearing plate is installed, the upper part of the load-bearing plate 7 is rotated and set in the slag discharge channel 4, and the load-bearing plate 7 is arranged obliquely.

[0025] Specifically, the bearing plate 7 includes a rotating shaft 71 and a rectangular plate body 72 disposed on the rotating shaft 71, and the rotating shaft 71 and the plate body 72 are welded into an integral structure. Mounting bolts 10 are disposed at both ends of the rotating shaft 71, and the mounting bolts 10 are penetrated on the side walls of the slag discharge channel 4. The bearing plate 7 is rotatably connected between the two side walls of the slag discharge channel 4 through two mounting bolts 10, and the bearing plate 7 can be rotated in the slag discharge channel 4 by a certain angle.

[0026] A compression spring 9 is arranged between the lower part of the load-bearing plate 7 and the side wall of the slag discharge channel 4. The function of the compression spring 9 is to ensure that the side wall of the slag discharge channel 4 does not fit the load-bearing plate 7, and the two should maintain a certain angle. When the compression spring 9 is installed, a plurality of limit bolts 11 are arranged at intervals below the load-bearing plate 7. The plurality of limit bolts 11 are arranged along the length direction of the load-bearing plate 7. Each limit bolt 11 passes through the load-bearing plate 7 and is connected to a compression spring 9, that is, the limit bolts 11 and the compression springs 9 correspond one to one.

[0027] The compression spring 9 is sleeved on the limiting bolt 11, and the two ends of the compression spring 9 are tightly pressed between the load-bearing plate 7 and the inner wall of the slag discharge channel 4. The limiting bolt 11 can realize the installation of the compression spring 9, and can also limit the compression spring 9 to prevent the compression spring 9 from being displaced and offset, and ensure that the compression spring 9 is in a certain position. Under the action of multiple compression springs 9, the load-bearing plate 7 can be supported so that it has a certain angle with the side wall of the slag discharge channel 4, and then the load-bearing plate 7 and the side wall of the slag discharge channel 4 are enclosed to form a triangular installation space 12.

[0028] A monitoring sensor 8 for monitoring the rotation of the load-bearing plate 7 is provided on the inner wall of the slag discharge channel 4. The monitoring sensor 8 adopts a micro switch. The monitoring sensor 8 is located in the installation space 12. The monitoring sensor 8 is connected to the controller 6, and then the monitoring signal is fed back to the controller 6. The controller 6 adopts a DCS controller 6.

[0029] The side wall of the slag discharge channel 4 where the monitoring sensor 8 is located and the bearing plate 7 form a variable angle, and the angle can be changed depending on the flow of slag. When the slag flows through the bearing plate 7, the bearing plate 7 is compressed and deflected, and then the compression spring 9 is compressed, and the bearing plate 7 contacts the monitoring sensor 8; when the slag stops flowing, under the action of the restoring force of the compression spring 9, the bearing plate 7 deflects in the opposite direction and no longer contacts the monitoring sensor 8.

[0030] The principle of the utility model is as follows: when the ash and slag normally fall in the slag discharge shaft 2, the slag discharger 3 operates normally, and the fallen ash and slag are continuously pushed along the slag discharge channel 4. The ash and slag must continuously pass through the load-bearing plate 7 during the flow in the slag discharge channel 4. When the ash and slag pass through the load-bearing plate 7, the load-bearing plate 7 is deflected by the pressure, and then the load-bearing plate 7 compresses the monitoring sensor 8, and then the controller 6 receives the signal. Since the ash and slag will continuously pass through the load-bearing plate 7, the controller 6 will continuously receive the signal.

[0031] Once the slag discharge shaft 2 is blocked, the slag cannot fall down. Therefore, even if the slag discharger 3 is running, it cannot push the slag forward due to the lack of slag, and the slag cannot flow to the position of the load-bearing plate 7, and the slag cannot pass through the load-bearing plate 7. At this time, the load-bearing plate 7 rotates in the opposite direction under the action of the compression spring 9 due to the lack of external pressure, and the load-bearing plate 7 no longer contacts the monitoring sensor 8. The monitoring sensor 8 also transmits a signal to the controller 6, prompting the personnel in the main control room that the slag discharge shaft 2 may be blocked, so that personnel can be arranged to go to the site for timely processing.

[0032] In the process of ash flow, in order to ensure the smooth rotation of the bearing plate 7 and avoid jamming, a transition thin plate 13 is further provided in the slag discharge channel 4, and the transition thin plate 13 is bent and overlapped on the rotating shaft 71 above the bearing plate 7. When the ash flows, the transition thin plate 13 plays a certain blocking role, and the ash on the transition thin plate 13 can flow quickly to the bearing plate 7, avoiding the accumulation of ash near the rotating shaft 71, and improving the smoothness of the rotation of the bearing plate 7.

[0033] At the same time, guide plates 14 are symmetrically arranged on both sides of the bearing plate 7. The function of the guide plates 14 is to reduce the flow of ash at the two ends of the length direction of the bearing plate 7. The guide plates 14 on both sides are arranged in an inverted "eight" shape, and the guide plates 14 and the bearing plate 7 are surrounded to form a chute structure. Along the flow direction of the ash, the height of the guide plates 14 gradually increases. The guide plates 14 make the ash flow through the bearing plate 7 and gather in the middle of the bearing plate 7, so as to reduce the ash at the end of the bearing plate 7 as much as possible, and avoid the ash from being stuck between the end face of the bearing plate 7 and the side wall of the slag discharge channel 4, which is also a measure to improve the smoothness of the rotation of the bearing plate 7.

[0034] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
